Introduction to the Invoicing

Service API

PayPal enables you to create and manage invoices. When you send an invoice, PayPal emails

the receipient and allows him or her to pay with PayPal.

The following diagram shows the basic execution flow for creating and sending an invoice:

The circled numbers indicate actions that you take as well as actions taken by PayPal and your

customer:

1. Specify the contents of the invoice in the CreateInvoice request and send the request to

the https://svcs.paypal.com/Invoice/CreateInvoice endpoint.

2. Examine the response and verify that the ACK field contains SUCCESS.

3. Using the invoice ID in the response, create a SendInvoice request and send it to the

https://svcs.paypal.com/Invoice/SendInvoice endpoint.

4. Examine the response and verify that the ACK field contains SUCCESS.

NOTE: You can combine the creation and transmission of an invoice in the same request,

which is CreateAndSend. After you create the request, send it to the

https://svcs.paypal.com/Invoice/CreateAndSendInvoice endpoint.

5. If the SendInvoice request was successful, PayPal sends an invoice by email to the payer

whose email you specified in the CreateInvoice or CreateAndSendInvoice request.

6. When your customer clicks Pay Invoice in the email, the customer’s browser is redirected

to PayPal and the customer is prompted to log in.

7. The customer can then pay on PayPal.

The contents of an invoice depend on what you specify in the CreateInvoice, or

CreateAndSend requests. Following is an example invoice:

Introduction to the Invoicing Service API

Sending Invoices on Behalf of a Merchant

1

Sending Invoices on Behalf of a Merchant

You can send invoices on behalf of a merchant if you have permission to do so. There is no

difference in how you set up your request for CreateInvoice or

CreateAndSendInvoice, except that you specify the merchant’s email address instead of

your own in the request, and you include an additional header that indicates you have the

permission of the third party to send invoices on their behalf.

The merchant grants you permission using their PayPal profile, or you request permission

using the Permissions Service API. For more information about this API, see PayPal

Permissions Service at

PayPal Permissions Service.

Invoicing Service API Operations

The operations in the Invoicing Service API enable you to create and send invoices to your

customers, as well manage existing invoices, which may or may not have been sent.

NOTE: Although you do not need to register your application with PayPal, you must have a

valid app ID to use the Invoicing Service API. If you have an existing app ID, you can

reuse it. See

x.com to obtain an app ID.

Invoicing Service API Examples

You can use the Invoicing Service API to create, send, update, cancel, or obtain details of

invoices for yourself or third-party merchants. You can also search invoices, and mark them as

paid, unpaid, or refunded.

HTTP Headers

Each request message includes HTTP headers specifying authentication, the application ID,

the device ID or IP address, and the payload format or protocol (SOAP).

Adaptive Payments supports request bodies with JSON, NVP, and XML data formats for

REST implementations. You can specify different formats for the request and response, such

as sending the request in JSON and requesting an XML response.

For SOAP, you must also include a specific SOAP protocol header (see the SOAP messages

section).

The following is an example of HTTP headers for NVP in Java for a web implementation:

headers.put("X-PAYPAL-SECURITY-USERID", "tok261_biz_api.abc.com");

headers.put("X-PAYPAL-SECURITY-PASSWORD","1244612379");

headers.put("X-PAYPAL-SECURITY-SIGNATURE","lkfg9groingghb4uw5"

headers.put("X-PAYPAL-DEVICE-IPADDRESS", "168.212.226.204");

headers.put("X-PAYPAL-REQUEST-DATA-FORMAT", "NV");

headers.put("X-PAYPAL-RESPONSE-DATA-FORMAT", "NV");

headers.put("X-PAYPAL-APPLICATION-ID", "APP-80W284485P519543T");

NOTE: HTTP headers are case sensitive.

Authentication

Use your PayPal account API credentials to authenticate your application. Your API

credentials include an API username and API password. If you are using 3-token

authentication, you must also specify an API signature. If you are using a certificate, the

certificate is used with the username and password; the signature is not used. To specify API

credentials, include the following HTTP headers in your request message (observing case

sensitivity):

HTTP Headers for Authentication

Specifying JSON, NVP, or XML Data Formats

Use the HTTP header X-PAYPAL-REQUEST-DATA-FORMAT to specify the data format the

request body. You can send messages using JSON, NVP or straight XML.

Use the and X-PAYPAL-RESPONSE-DATA-FORMAT headers to specify the data format for the

response.

For SOAP messages, refer to the next section.

HTTP Headers for JSON, NVP, and XML Data Formats

Header Description

X-PAYPAL-SECURITY-USERID Your API username

X-PAYPAL-SECURITY-PASSWORD Your API password

X-PAYPAL-SECURITY-SIGNATURE Your API signature, which is required only if you use 3-

token authorization; a certificate does not use a signature

X-PAYPAL-SECURITY-SUBJECT Third-party permission specification, which specifies the

email address or phone number (for mobile) of the party on

whose behalf you are calling the API operation. The subject

must grant you third-party access in their PayPal profile.

NOTE: Resources specified by the API operation, such as a

payment or preapproval identified by a key, must be

owned by the subject granting the third-party

permission.

Header Description

X-PAYPAL-REQUEST-DATA-FORMAT The payload format for the request.

Allowable values are:

 NV – Name-value pairs

 XML – Extensible markup language

 JSON – JavaScript object notation

X-PAYPAL-RESPONSE-DATA-FORMAT The payload format for the response.

Allowable values are:

 NV – Name-value pairs

 XML – Extensible markup language

 JSON – JavaScript object notation

SOAP Messages

To use Adaptive Payments with SOAP, include the HTTP headers for authentication as

described in the section Authentication and the application ID as described in the next section.

In addition, include the X-PAYPAL-MESSAGE-PROTOCOL header with a SOAP11 value.

The following is a header example for an Adaptive Payments API call for a SOAP message:

headers.put("X-PAYPAL-SECURITY-USERID", "tok261_biz_api.abc.com");

headers.put("X-PAYPAL-SECURITY-PASSWORD","1244612379");

headers.put("X-PAYPAL-SECURITY-SIGNATURE","lkfg9groingghb4uw5"

headers.put("X-PAYPAL-DEVICE-IPADDRESS", "168.212.226.204");

headers.put("X-PAYPAL-MESSAGE-PROTOCOL", "SOAP11");

headers.put("X-PAYPAL-APPLICATION-ID","APP-80W284485P519543T");

Below are the service name, port type, binding and location for SOAP as defined in the

Adaptive Payments WSDL.

<wsdl:service name="AdaptivePayments">

<wsdl:port name="AdaptivePaymentsSOAP11_http"

<binding="services:AdaptivePaymentsSOAP11Binding">

<soap:address location="https://svcs.paypal.com/AdaptivePayments" />

Specifying Application and Device Information

You also must identify the application. You can optionally identify other information

associated with the client and the API version:

HTTP Headers for Application and Device identification

Header Description

X-PAYPAL-APPLICATION-ID (Required) Your application’s identification, which is issued

by PayPal.

NOTE: Check X.com for which application ID must be

defined for working in the sandbox.

X-PAYPAL-DEVICE-ID (Optional) Client’s device ID, such as a mobile device’s

IMEI number or a web browser cookie.

X-PAYPAL-DEVICE-IPADDRESS (Required) Client’s IP address.

X-PAYPAL-SERVICE-VERSION (Optional) The version of an API operation to use. By

default, PayPal executes a request with the current version

of an API operation.

NOTE: PayPal recommends not specifying a version unless

it is absolutely required.
